A. WYGKOFF, OF WELLSBURG, NEWYORK.

MACHI-NE FOR MAKING LINKS or JACK-CHAINS.

Specification of Letters Patent No. 10,528, dated February 14, 1854.

To all whom it may concern Be it known that I, ARCALQUS Wronorr, of Wellsburg, in the county of Ghemung and State of New York, have invented a new and useful Improvement in Machines for Making Links for Chains; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side elevation of the machine for forming the links. Fig. 2 is a birds eye view, of the same; Fig. 3, a detached view exhibiting on the under side, the cutter and bender of the wire in the horizontal movement thereof; Fig. 4, a detached view of a portion of Fig. 1, (the part Fig. 3 being removed) to exhibit the action of vertical bender, sleeve, and lever, giving the middle bend, &c.

The nature of my improvement in power machines for making links for chains, consists in giving the grip, and middle bend of the link, cutting the wire to' the requisite length and bending both ends thereof simul-' taneously; and by an automatic movement, deliver the formed link, ready for joining in a continuous chain. v

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In Fig. 1, X X represents a solid table supported 'at a suitable height. A, is the pulley to which the power is applied carrying on its shaft a pinion B, giving motion to the driving wheel C. D and E are cams on the horizontal shaft 0 for operating the bars 0, and N. F is a large cam also on the shaft C, which striking against the end of the bar H, carrying rack H, gives an intermittent motion to the pinion K, placed on the vertical shaft 5. This shaft 5 also carries a bevel pinion K (placed under'K for giving motion to L carrying a sleeve 6, (see Fig. 4) on the outer end of which is a bending arm 7, which in its semi revolution forms one eye of the link. M is a pinion (driven by K) which is placed on a vertical shaft, also carrying a sleeve, on the end of which is secured the knife or die f, for cutting the wire into suitable lengths, and likewise for bending the other eye of each link.

0, is a bar moved by cam E. It operates a lever-R, for giving the middle bend to the link, and holding or clamping the wire,

by a set screw) for graduating the pressure of the angular end of the slide bar 0, on the lever B, in giving the middle bend and grip to the link. Y is a sliding barfor closing the opening 8 through which the wire is fed. It is pressed by theback of the cutter while being out, by f, and stationary die g, I

f, which contracts the helical spring 10, on

the shank of Y, this spring reacts the moment the pressure is removed and the bar Y is forced back and closes the opening, 8,

while the eyes of the link are forming. T, I

T, are small fiat springs having stub bolts or pins working in inclinedgrooves in the ends of the sleeves on pinions M and L. They are for the purpose of throwing off the link formed on the mandrels c and b;

the mandrel b is the one around which the end of the wire is carried horizontally by the die f, in forming one eye, and 0 is the mandrel around which the wire is carried vertically by the bender 7, on the sleeve of L, simultaneouslywith the formation of the other eye on I). G is a cam secured on the side of cam F and in its revolution operating on lever I, draws back the rack giving a reverse movement to all thepinions,

except B.' The rod Y being moved by the back of the die f, permits the wire to'be fed in opening 8.

introduced in opening 8, and held at a slight angle, is forced against the adjustable stop 12, passing through a guide. near to that side. The angular projection 4, on lever B is brought to bear diagonally on the wire, and forcing it up betweenthe pins. 0 and b,

. X The operation is as follows: A wire being by means of cam E operating on bar 0, and

forcing the angular projection thereon' I 1 under the lever It raises it, and thus gives the middle bend to the wire, and securely clamping it between the pins and against the plates. The die f, is now moved by the semi-revolution of pinion M acted on-by bar N and cam D, and cuts ofi the wire rod the requisite length for a link, at the same time carrying it. horizontally around the pin or mandrel 6, while the bender 7 on the sleeve of pinion L simultaneously carries the other end around the pin 0, L receiving its motion from the miter wheel K, under K, said K being actuated by the sliding rack H, and

cam F, and completes the link; the springs '1, T, are now forced outward by the pins working in incline grooves on theends of the sleeves, and thus slide the eyes off the pins or mandrels 0 and b, and the link drops from the machine ready for joining, which may be done by closing the eyes by hand,"

but much more perfectly by machinery.

Having described my improvement for manufacturing chains, what I claim as my invention and desire to secure by Letters Patent is- The fixed stud pin 6 and stud pin 0, placed at right angles to each other, in combina; tion with the wiper and cutter f, and cutter 5 7, operated in the manner set forth for the purpose ofbending the two eyes of the link ofjack chains simultaneously.

In testimony whereof I have hereunto signed mynamebefore two subscribing wit- 2 nesses. a g
